Title: Reduced print method for picture element data
Inventor: TAKEDA HIDETOSHI
IPC: G06T3/40
Filed: 1990-03-22
Abstract: PURPOSE:To avoid a missing picture by generating a mask pattern signal in which a reduction rate is kept identical and only a signal pattern is made different for each line and printing out the data while the interleaving position of the picture element data is differentiated from each line. CONSTITUTION:A read picture element data is not processed but read synchronously with a mask pattern signal generated in advance in response to a set reduction rate at print and print heads 4a, 4b are driven so as to interleave a picture element data for each line according to the mask pattern signal. In this case, since the mask pattern signal is generated to have a different pattern from each line while keeping a same reduction rate, the picture element to be interleaved from the picture element data differs from each line. Since the picture data printed out with interleaving is not coincident with each line, complete missing of part of an original picture is not caused.

IPC: H02N2/00
Filed: 1991-04-05
Abstract: PURPOSE:To easily move a body which is fixed to a piezoelectric element unit in optional directions by driving the piezoelectric element unit consisting of two piezoelectric groups which are different in array direction. CONSTITUTION:Actuators consist of piezoelectric element units 22a and 22b; and a voltage is impressed to 1st piezoelectric element groups which constitute the piezoelectric element units 22a and 22b and are arrayed in the same direction and then a voltage is impressed to 2nd piezoelectric element groups which are arrayed in a direction different from the direction. Further, the voltage impressed to the 2nd piezoelectric groups is ceased after the voltage impressed to the 1st piezoelectric element groups is ceased, and the operation is repeated to move the displaced members 12 which are fixed to the 2nd piezoelectric element groups periodically in a specific direction. Consequently, the displacing force of the piezoelectric elements is effectively utilized to easily move the bodies fixed to the piezoelectric element units 22a and 22b in optional directions.
